JAMES H. LEONARD, OF EAST ORANGE, NEW JERSEY, ASSIGNOR TO A. 'B. SANDS&, SON CO OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

TRAP FOR BATHTUBS, &c.

To all whom it may concern:

Be it known that I, .JAMES H. LEONARD, a citizen of theUnited States,residing at 158 No. Arlington Ave, East Orange, in the State of NewJersey, have invented certain new and useful Improvements in Traps forBathtubs, &c., of which the following is a specification, referencebeing had to the accompanying drawings, forming a part hereof.

The object of this invention is to provide an improved trap andconnection for use with bathtubs, lavatories and other receptacles. Theinvention has been developed with particular reference to its use withlavatories, etc., on board ship, in which the trap is below the deckwhich supports the lavatory or other receptacle and must not only beconnected therewith by means which permit a tight joint between thereceptacle and the trap, but must be so constructed as to permit thehole in the deck through which the connections pass to be closedwater-tight, so that there can be no leakage through the deck. Theimproved fitting, however, is equally adapted for house use, where it is.desirable to prevent the possibility of the passage of water throughthe floor around the connection. The invention will be more fullyexplained hereinafter with reference to the accompanying drawing inwhich-the single figure, partly in vertical section and partly inelevation, shows the improved fitting with the deck or floor and aportion of the receptacle. I

In the construction illustrated there is shown at a a portion of abathtub or basin or other receptacle, the outlet of which is connectedthrough a horizontal pipe 22 and an elbow c with the vertical outletpipe 0?. The trap c, which is preferably of the nonsiphoning type, has asleeve 7", which is long enough to extend upwardly through the deck orfloor which supports the receptacle, the contents of which are to bedischarged through the trap. As shown, the deck or fioor comprises asteel plate 9 and an overlying concrete or composition body 71, with atop covering 2'. The neck or sleeve 7' for cooperation with such afloor, is screwthreaded for its entire length to receive packing devicesby means of which the hole through the deck or floor can be closedtightly against the passage of water. In

the construction shown the steel plate 9 is received between a shouldere of the trap e and a nut 7:,suitable packing being provided, as at Z,while the upper end of the sleeve receives, above the deck or floor, another packing nut m with suitable packing a. The vertical outlet pipe d,connected with the receptacle as above described, is extended downwardwithin the sleeve f into the body of the trap e and a packing nut 0surrounds the outlet pipe and engages the sleeve 7 so as to make a tightjoint between the outlet pipe and the upper end of the sleeve. The trapc is provided with the usual outlet p, above the lower end of the outletpipe cl, and is also provided with the usual clean-out plug 9. 7

It will be seen that by means of the described fitting not only is atight joint assured between the outlet pipe and the trap, but thepassage of water through the deck, around the trap sleeve or neck iseffectually prevented.

It will be understood that various changes in details of constructionwill be made to suit different conditions of use and that the inventionis not restricted to the precise construction shown and describedherein.

I claim as invention:

1. The combination of a receptacle to be placed above a floor, a traphaving a sleeve extended upward therefrom through the floor, externalpacking devices applied to the sleeve to form a tight joint between thesame and the floor, and an outlet pipe connected with the receptacle andwith said sleeve, the outlet pipe being extended downward within thetrap and the trap having an outlet above the lower end of the outletpipe.

2. The combination of a receptacle to be placed above a floor, a traphaving a sleeve extended upward therefrom through the floor, externalpacking devices applied to the sleeve to form a tight joint between thesame and the floor, an outlet pipe connected with the receptacle andwith said sleeve, and a packing device to close the joint between theoutlet pipe and the upper end of the sleeve. I

3. The combination of a supporting floor, a receptacle above the same, atrap below the floor and having a sleeve extended upward through thefloor, an outlet pipe connected with the receptacle and with the sleeve,and packing devices to close tightly the opening in the floor around thesleeve.

4. The combination of a supporting floor, a receptacle above the same, atrap below the floor and having a sleeve extended upward through thefloor, an outlet pipe connected a receptacle above thersame, a trapbelow the floor and having a sleeve extended upward through the floor,an outlet pipe connected with the receptacle and extended downwardthrough the sleeve within the trap, packing devices cooperating with thesleeve and the floor to close tightly the hole with the receptacle andextended downward'through the floor around the sleeve, and a within thetrap, the latter having an outlet above the lower end of said outletpipe, and packing devices cooperating with the sleeve and the floor toclose tightly the hole through the floor around the sleeve.

5. The combination of a supporting floor,

packing device 'to close the joint between the outlet pipe and thesleeve at the upper end of the latter. 7
